Table 1 | Summary of data

Lineage Country Sequence count Earliest sequence Travel history
B.1.351 South_Africa 259, UK 1 260 2020-10-08
B.1.1.7 UK 4249, Italy 11, Denmark 9, Ireland 7, Netherlands 3, Australia 3, Hong_Kong 2, Singapore 1, Israel 1, France 1 4287 2020-09-20

Lineage B.1.351

Caveat: Most locations outside the original focus have not reported sustained transmission and many cases have known travel links to the focal location. Increasing numbers of international cases is currently likely due to increased surveillance and vigilance.

The number of ticketed origin-to-destination journeys from London airports to countries outside the United Kingdom during October 2020.

Colours indicate numbers of published genomes of B.1.1.7 deposited on GISAID as of December 26, 2020. Grey bars indicate countries that have reported the presence of the variant but have not yet published B.1.1.7 sequences on GISAID as of the 26-Dec-2020. White bars indicate countries with no reports of B.1.1.7.

Flight data come from the International Air Transportation Association that capture anonymized, passenger-level flight itinerary data, comprising both commercial flights and scheduled charter flights. These data account for ~90% of global air travel volumes, with the remaining volumes modelled using market intelligence. We report data from destinations including >5,000 passengers.
